INCORPORATED, OF WHITINSVILLE, MAS- SPINNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 777,915, dated December20, 1904.

' Application filed December 21, 1903. Serial No. 185,950.

To all whom it may concern:

Be it known that I, HENRY A. OWEN, a citizen of the United States,residing at Whitinsville, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement inSpinning-Machines, of which the following is a specification.

This invention has reference to an improvement in spinning-machines, andmore particularly to an improvement in that form of spinning-machinesknown in the art as twisters.

In certain fancy weaves of cloth it is required to use a thread havingbunches formed at intervals on the thread to give the required result inthe weave of the cloth.

The object of my invention is to form a thread having bunches apredetermined distance apart, and I accomplish this object by mechanismin a spinning or similar machine adapted to intermittently revolve thefeedrolls and by the way in which the strands forming the thread are runthrough the feedrolls and guide-eyes on the linger-boards.

In twisting-machines to which my improvement is particularly adapted twosets of feedrolls are used, one above theother. With my improvedmechanism for forming bunches on the thread at intervals any number ofstrands may be used. Where three strands are used to form the thread,two of the strands are fed downward through the lower set of feed-rollsand guide-eye on the finger-board in the usual way. The third strand isfed clownward through the upper set of feed-rolls to the outside of theguide-eye on the fingerboard, where it enters the guide-eye between thecoil forming the eye. It is now twisted with the two strands for apredetermined distance and then wound on the two strands to form abunch, these operations being repeated indefinitely.

My invention consists in the peculiar and novel construction ofmechanism in a spinningmachine adapted to form bunches on the threads atintervals and to give a uniform twist to the thread between the bunches,said mechanism consisting of gearing, clutches, and an intermittentmotion, the whole adapted to automatically stop the lower feed-rolls,while the upper feed-rolls are revolved to feed the strand that .formsthe bunch and then to revolve both the lower and upper feed-rolls at thesame ratio and feed all the strands simultaneously to form a uniformtwist between the bunches, as will be more fully set forth hereinafter.

In the drawings enough of a twisting-machine is shown to clearly showthe adaptation of my invention.

. Figure 1 is a vertical view looking at the left-hand end of atwisting-machine, showing the improved gearing and clutch mechanismconnected withthe left-hand end of the feedrolls and the methodofcarrying the strands downward through the feed-rolls and the guideeyeson the finger-boards. Fig. 2 is a vertical view looking at theright-hand b'oX end of the twister with the cover of the end removed,showing the gearing connecting with the intermittent-motion mechanism.Fig. 3 is a vertical sectional view looking from the right-hand end ofthe machine, showing the intermittentmotion mechanism connected with therighthand end of the lower set of feed-rolls and the gearing and clutchmechanism connected with the right-hand end of the upper set offeed-rolls. Fig. 4 is a front vertical view of the left-hand end of themachine, showing the gear on'the lower feed-roll connected to the gearon the upper feedroll through double intermediate gears having a clutchmechanism. Fig. 5 is a front vertical View of the right-hand end of themachine, showing the gearing in the box end in broken lines connectingwith the upper feed-roll through double intermediate gears having aclutch mechanism and to the intermittent motion connecting with thelower feed-roll. Fig. 6 is an enlarged view of the inner right-handintermediate gear, showing the pawl and ratchet forming the clutch ofthe gears. Figs. 7 and 8 are transverse sectional views of the left andright hand double intermediate gears, showing them in their relativepositions. Fig. 9 is an enlarged detail view of a fingerboard guide-eye,showing the method of running the strands through the eye of theguideeye; and Fig. 10 is a transverse sectional view through the coilforming the eye of the guideeye, showing the single strand passingbetween the coil and winding on the two strands to form a bunch on thethread.

In the drawings, (1, indicates the right-hand box-end frame, and a theleft-hand end frame supporting the front rail (4 which in turn supportsthe finger boards a (o with the guide-eyes a a. The roller-stands a aare supported on the front rail a and have the usual brackets a a,constructed to form bearings for the lower bottom roll cf, the upperbottom roll a and the top rolls a a and to support the bars (0 (0 havingthe guideeyes a a. On the top of the roller-stands a a is secured theguide-rod a and on the outer ends of the lower brackets a a theguide-rod (0 both of which extend the length of the machine.

The shaft 6 extends through a bearing in the box-end frame a and has onits outer end in the frame the usual front-roll gear a, operated througha train of gears in the frame. The shaft 6 is in alinement with theshaft of the lower bottom roll a but has no connection with it. On theshaft 6 in the frame a is the gear 7), meshing with the intermediategear 6 which in turn meshes with the gear 6 on the shaft 1), extendingthrough a hearing in the frame a. The intermediate gear 6 is supportedon the stud 6 secured to the end frame a.

On the inner end of the shaft 6 is secured the gear 0, and in the samerelative position is secured a corresponding gear 0 on the lefthand endof the lower bottom roll shaft. These gears c 0 mesh with the outerintermediate clutch-gears 0 0, having the spring-pressed pawls c 0engaging with the ratchets c 0 on the inner intermediate clutch-gears c0 which mesh with the gears c 0 secured on the outer ends of the upperbottom roll shaft, as shown in Figs. 4 and 5. The intermediateclutchgears c 0 and 0* c are loosely mounted on the studs 0 0, supportedon the brackets c 0 secured to the roller-stands a a at each end of themachine.

The upwardly-extending bracket d is secured to the front rail a at theright-hand end of the machine and supports the stud d, on which isloosely mounted the gear d meshing with the gear (Z secured on therighthand end of the lower bottom roll shaft. On the gear (Z and forminga part of it is the wheel (Z havinga plurality of notches 03 6F,extending inward from its periphery, which is concaved between thenotches. On the inner end of the shaft 1) is secured the disk 03, havingthe pin (Z7 in a position to engage with one of the notches d in thewheel d at each revolution of the disk at. The periphery of the disk dfits into the concave portions of the periphery of the wheel (i when thepin leaves the notches, holding the lower bottom roll (a from revolvingthrough the gears (Z and (i until the pin has traveled approximately arevolution and entered the next notch in the wheel. As shown in Fig. 3,the wheel (Z has five notches and is given one-fifth of a revolution toone revolution of the disk cl.

The thread 6 may be composed of any number of strands desired. In thepreferred form I use three strands a, a and c and form the bunches e eon the thread by twisting the strand 6 around the strands e and 6 asshown in Figs. 9 and 10. The strands and e are carried downward over theguide rod a, through the guide-eye a on the lower bar (0 then throughthe lower feed-rolls a and a and the guide-eye a on the finger-board inthe usual way. The strand 6 is carried downward through the guide-eye aon the upper bar (4 then through the upper feed-rolls a and a, over theguide-rod (0 to the outside of the guide-eye a, which it enters throughthe coil forming the eye of the guide-eye. It is now twisted on thestrands e and e to form the bunch a and then twisted with the strands cand c to form a uniform twist between the bunches.

In the operation of my improved mechanism adapted to spinning or similarmachines for forming bunches on threads at intervals the lowerfeed-rolls a and a are held from revolving by the periphery of the diskd en: gaging with the concave portions of the periphery of the wheel dfor approximately one revolution of the disk d. This holds the strands eand 0 while the strand 6 is fed to form the bunch, the upper feed-rollsbeing revolved from the shaft I), through the gear 0, meshing with theouter clutch-gear 0, the pawl 0 and the ratchet c on the innerclutchgear 0, meshing with the gear 0 on the righthand end of the upperfeed-roll shaft. The gears 0, 0,c ,and 0" all have the same pitch andrevolve the upper feed-rolls at the same ratio as the shaft 6. When thelower feed-roll is held from revolving, the ratchet c on the innerintermediate clutch-gear c at the left-hand end of the machine revolvesin the direction of the arrow, as shown in Fig. 1, the ratchet slippingunder the pawl c on the outer intermediate clutch-gear c. When the diskd 6 has approximately completed its revolution, the pin (Z on the diskenters one of the notches in the wheel d and revolves it one-fifth of arevolution. The lower and upper set of feed-rolls are now revolved atthe same ratio through the gear (Z meshing with the gear 6Z3 on theshaft of the lower bottom feed-roll a at the right-hand end of themachine, then through the gear 0 on the shaft of the bottom feed-roll aatthe left-hand end, meshing with the outer intermediate clutcl1gear 0,having the pawl 0 engaging with the ratchet c on the inner clutch-gear0*, which meshes with the gear 0", secured on the left-hand end of theupper ICC feed-roll shaft. This feeds all the strands of the thread atthe same ratio for a predetermined distance and gives a uniform twist tothe thread between the bunches. When both the lower and upper feed-rollsare revolved at the same ratio, the ratchet c on the inner intermediategear at the right-hand end of the machine revolves in the direction ofthe arrow, as shown in- Fig. 3, the ratchet slipping under the pawl c onthe outer intermediate clutch-gear c.

As shown in the drawings, the mechanism is adjusted to give two-thirdsofa revolution to the upper feed-rolls to feed the strand 6 to form thebunch and one-third of a revolution to both lower and upper feed-rollsto feed all the strands to form the twist between the bunches. Thisratio may be varied when required by changing the pitch of the gearing.In twisting threads of this nature it is desirable to give a slow motionto the upper feed-rolls in forming the bunch and a quick motion to bothsets of feed-rolls in forming the twist between the bunches.' This isaccomplished by making the pitch of the gear 5 on the shaft 6 greaterthan the pitch of the gear 6 on the shaft 6* and the pitch of the gear(Z on the stud cl greater than the pitch of the gear (Z on the shaft ofthe lower feedroll, as shown in Figs. 2, 3, and 5.

It is evident that any form of a clutch may be used between theintermediate clutch-gears 0' and c and that any combination of strandsmay be used to form the bunches and the uniform twist between thebunches on the thread without materially affecting the spirit of myinvention.

Having thus described my invention, I claim as new and desire tosecureby Letters Patent 1. In a spinning-machine, the combination of twosets of feed-rolls and finger-boards with guide-eyes, of means forrunning two strands through one set of feed-rolls and a guide-eye, meansfor running a third strand through the other set of feed-rolls to theoutside of the guide-eye, then between the coil forming the eye of theguide-eye to merge with the two strands in the guide-eye, and mechanismadapted to give an automatic and continuous intermittent motion to thefeed-rolls to hold the two strands while the third strand is fed to forma bunch on the two strands, and then to feed all the strandssimultaneously to form a uniform twist between the bunches, asdescribed.
